    tenance requirement is first calculated, taking into account the size of the animal. To this is added the amount neces¬ sary to produce the milk, taking into account the amount and richness. For example, let it be assumed the problem is to calculate the ration for a 1150-pound cow producing 30 pounds of 4.5 per cent milk daily. According to the pre¬ ceding statements the requirements would be as follows: Digestible Protein Pounds Total Nutriment Maintenance 1150 lb. 30 lb. 4.5% milk . . Total. (.070 X 11.5) .81 (30 X .069) 2.07 2.88 (.79 X 11.5) 9.09 (30 x 38) 11.40 20.49 The ration to be fed will then be selected and calculated using the average composition of feeds as given in Table 51, making such changes and modifications as are seen to be necessary in order to bring the composition of the ration reasonably close to the standard.
